Question
Hi
Have a newer Tecumseh Model 143.024200 4.25hp mower but no manual. Cannot find oil drain plug.  On bottom of engine there are two nobs that are round and also a hole that appears to take a large allen key. please advise. thanks.

Answer
 Hello Gary:

 The Oil Drain Plug is the Allen Plug you see on the Bottom. Go to this Addy http://www3.sears.com/ and Click on the Box for Lawn Equipment. Then Follow the Directions to the View Diagram/Parts List Page. Select View Diagram and Click Continue.  # 72 on the Diagram is the Oil Plug. Hope this Helps. Let me know what Happens, Please. I enjoy knowing the Outcome. Thanks.

 Good Luck

 Respectfully

 John
